我試圖更新購物車會話中的數量,但下面的代碼只增加了第一個項目的數量,然後在兩次添加任何其他項目時執行合併,kidly幫助在php中使用會話將項目添加到購物車
$('.add-to-cart-mt').on('click', function(e){
e.preventDefault();
var id =$(this).attr('id');
$('#add-to-cat-dialog').dialog({
autoOpen:false,
modal:true,
hide:"pluff",
show:"slide",
height:200,
open: function() { $(".ui-dialog-titlebar-close").hide(); },
buttons:{
"Add":function(){
$('#add-to-cat-dialog').dialog("close");
$.ajax({
url: 'add_to_cart.php',
data: { productId : id },
success: function (data) {
$('.top-cart-contain').empty();
$('.top-cart-contain').load("header_cart_summary.php");
},
error :function (data, textStatus, jqXHR) { }
});
},
"Cancel":function(){
$(this).dialog("close");
}
}
});
$('#add-to-cat-dialog').dialog("open");
});
session_start();

$productDetail= mysqli_fetch_assoc($productById);
$itemArray = array(
$productDetail["productId"]=>array(
'name'=>$productDetail["productName"],
'id'=>$productDetail["productId"],
'quantity'=>1,
'price'=>$productDetail["productPrice"],
'image'=>$productDetail["productsImage1"]

);
if(!empty($_SESSION["cart_item"])) {

$_SESSION["cart_item"][$k]["quantity"] = 0;
}
$_SESSION["cart_item"][$k]["quantity"] += 1;
}
}
} else {

//set product count in the bag

你能'的var_dump($ _ GET [ '的productId']);'添加一個項目到購物車後?它說什麼? – proofzy
字符串(1)「5」:其中5表示產品Id的值。 – Ayuka
